Anthropic says an AI security startup's logo looks too much like its own

AI company Anthropic is suing cybersecurity firm Abnormal AI for trademark infringement, claiming their rebranded logo is too similar to Anthropic’s own and could confuse customers in the AI and cybersecurity sectors. Abnormal AI disputes this, stating their logo predates Anthropic’s wider public presence and that they operate in distinct markets. The lawsuit seeks to bar Abnormal AI from using the disputed logo and profits derived from it, while Abnormal AI claims the demands go beyond a simple design fix.
